Compatible Replacement & Equivalent Models
When the GV6-U12E-NK is unavailable or discontinued, the following models offer functional equivalence or drop-in compatibility. Always verify firmware, feedback type, and bus protocol before substitution.
- Parker GV6-U12E — Same current rating, standard EtherNet/IP variant (without NK option)
- Parker GV6-U16E-NK — Uprated to 16 A; pin-compatible, suitable for higher-torque motors
- Parker Compax3 C3S025V4 — Compax3 platform equivalent; requires parameter migration
- Parker Compax3 C3S075V4 — Higher power Compax3 replacement for demanding axes
- Kollmorgen AKD-P00306 — Third-party equivalent; EtherNet/IP, 3 A cont. (verify motor match)
- Yaskawa SGDV-2R8A01A — Cross-brand alternative; confirm bus and feedback compatibility
Note: Cross-brand replacements require re-commissioning and parameter re-mapping. Contact our engineers for a compatibility assessment.

- Printing and converting equipment
- Robotics end-of-arm tooling and collaborative robot joints
- Medical device manufacturing lines
System Compatibility
- PLCs: Allen-Bradley ControlLogix / CompactLogix (EtherNet/IP native), Siemens S7 (via EIP adapter), Omron NJ/NX series
- Motors: Parker MPP, MPJ, SM series brushless servo motors; third-party motors with standard encoder interface
- Software: Parker Motion Planner, ACR View, Compax3 ServoManager
- Bus Topology: EtherNet/IP linear, ring (DLR), and star configurations
Selection Guide
Use the table below to select the correct GV6 variant for your application:
- Current rating: Match drive continuous current ≥ motor rated current × 1.1 safety factor
- Bus protocol: U = Universal (multi-protocol); E suffix = EtherNet/IP; P suffix = PROFIBUS; S suffix = Sercos
- Feedback type: NK = No Keypad (panel-mount, remote HMI); standard = integrated keypad
- Voltage range: Confirm single-phase vs. three-phase supply availability at installation site
- Regeneration: Add external regen resistor for high-inertia or frequent deceleration cycles

Replacement & Compatibility FAQ
Q: Is the GV6-U12E-NK still in production?
A: Parker has transitioned the GV6 line to the Compax3 platform. New production may be limited — contact us to confirm current stock availability.
Q: Can I replace a GV6-U12E-NK with a Compax3 drive directly?
A: Mechanically yes, but you will need to re-configure parameters using Compax3 ServoManager and update your PLC EDS/AOP files. Our team can assist with migration.
Q: What does the “NK” suffix mean?
A: NK indicates “No Keypad” — the drive is designed for remote HMI or software-only configuration, without an integrated front-panel keypad.
Q: Do you ship internationally?
A: Yes. We ship worldwide via DHL, FedEx, and sea freight. Lead time is typically 3–7 business days for in-stock items.
Q: Can you provide a Certificate of Conformance (CoC)?
A: Yes, CoC and test reports are available upon request for all new OEM units.
